(JÁRNKNÉ- "IRON KNEE") KNEE SLEEVES
Our 7mm POWER Sleeves are built for warriors. Engineered from high-strength neoprene, these sleeves deliver maximum compression, joint support, and rebound performance. With a secure, locked-in fit and a straight-cut design, they naturally guide your knee into proper alignment — giving you that explosive “pop” at the bottom of every lift.
At 29cm, Sterkur sleeves offer superior coverage for your knees, quads, and hamstrings — just under the 30cm competition limit — making them fully compliant with most powerlifting federations.
Support: Reinforces knee positioning and limits patella movement, enhancing joint stability and proprioception — helping your body stay in control under serious weight.
Compression: Encourages circulation to reduce pain and swelling, keeping you training harder for longer.
Performance: Our 7mm high-strength neoprene stores kinetic energy and releases it during extension, fueling you through squats, cleans, snatches, and everything in between.
Warmth & Comfort: Keeps your joints primed and ready while staying comfortable enough to wear through an entire session.
Sterkur Strength sleeves aren’t just gear — they’re armor.
Benefits:
PERFORMANCE BENEFITS OF STERKUR 7MM POWER SLEEVES
Enhanced Force Output & Rebound Efficiency
High-density 7mm neoprene stores and releases elastic energy during knee extension, supporting greater power generation in compound lifts.
Improved Neuromuscular Coordination
Increased proprioceptive feedback promotes more precise movement patterns and motor unit recruitment under load.
Optimized Joint Stabilization
Firm compression and anatomical straight-cut design assist in maintaining proper knee tracking and patellar alignment throughout dynamic movement.
Minimized Energy Leakage
Secure fit reduces unwanted joint laxity and instability, ensuring more efficient force transfer and reduced muscular compensation.
Accelerated Warm-Up & Thermal Retention
Neoprene insulation increases synovial fluid activity and maintains joint temperature, aiding in mobility and performance readiness.
Reduction in Pain & Discomfort
Consistent compression may alleviate pressure on sensitive knee structures, reducing pain symptoms during and post-training.
Decreased Risk of Injury & Tendon Irritation
Structural support helps limit excessive joint movement and shear forces that contribute to overuse injuries and tendonitis.

SIZING GUIDE
To find your ideal fit, measure the circumference around the center of your knee with your leg fully extended.
For a Standard Fit, choose the size that matches your measurement.
For Maximum Compression (Competition Fit), select one size down — but expect an extremely tight, performance-driven fit.
Note: This guide works for most athletes, but if you have notably large quads or calves, consider sizing up for comfort. Sleeves designed for maximum compression should not be worn for extended periods outside of training.
